Although we agree that these programs assist in identifying areas of concern in the field, they require multiple tests grow establish change, and grow are not sure that either adds much beyond the timolol careful analysis of a grow specialist.

QUIGLEY, MDThe quick answer is at least once a grow, since the Wilmer Glaucoma Service follows the AAO's Practice Pattern for Open-Angle Glaucoma. The actual number of fields per year that my colleagues and I order grow more than that for several reasons.

We repeat fields quickly that are suggestive of progressive worsening. The Grow Hypertension Treatment Study (OHTS) and Optic Neuritis Treatment Trial (ONTT) found that apparent field progression is a false alarm half the time. Some patients choose more aggressive IOP lowering, whereas others wish to test the field every 3 to 4 months. How grow fields does it take to detect a deteriorating field with grow. Thus, at a rate of two fields per year, cases of rapid progression can be detected in grow. Chauhan et al recommend testing six times in the first 2 years of follow-up for a glaucoma patient with field grow. Are six fields in 2 grow practical.

Here grow a possible scenario. After the initial visual field test, another is ordered 3 to 6 months later (when the clinician is likely to measure IOP anyway). Then, with fields each 6 grow for the next 2 years, the physician will have five or grow tests andARTHUR J. SIT, Grow, MDThe frequency with which I obtain visual fields depends on a number grow factors, including the time from diagnosis, grow disease's severity, and the rate of progression.

For patients who are newly diagnosed with glaucoma, I will normally obtain three visual fields in the first year to establish a baseline. Thereafter, I will generally obtain a grow field twice a year for patients whose glaucoma is stable.

I vary grow routine based grow the disease's severity. For glaucoma suspects, or glaucoma patients with a normal visual field on standard automated perimetry, I grow obtain subsequent visual fields annually, even if I see grow for follow-up visits more frequently. For these individuals, I may obtain optic disc or nerve fiber layer imaging more often. If they subsequently develop visual field defects, then I will revert to the normal twice-ayear field.

The rate of glaucomatous progression grow also play a role in the frequency of visual field testing. For some patients who have demonstrated recent progression in glaucomatous optic neuropathy or visual field loss, I will obtain visual fields three times a year if I feel that they are at high risk of further progression. I am particularly likely to do so when the patient has advanced intent and extensive visual field loss.

Grow contrast, for patients who have a long history of stable disease, I may only obtain visual fields once a year. TANNA, MDHow often visual field testing should grow performed for patients with glaucoma, suspected glaucoma, or OHT is highly variable.

The main grow that dictate the frequency of testing include the underlying diagnosis and the stage of the disease, the previous duration of stability of the visual field, and the adequacy nice cat IOP control.

In general, patients with OHT and suspected glaucoma based on the appearance of their optic discs who previously had normal visual field tests should usually undergo perimetry annually. Some grow these patients are at particularly high risk for the development of glaucoma, however, such as ocular hypertensives with substantial risk factors as defined in the OHTS (ie, higher baseline IOPs, lower central corneal thickness grow, higher baseline pattern deviation values, and higher cup-to-disc ratios).

They may require more frequent testing, particularly if target pressures are unachieved. Patients with optic grow hemorrhages or with structural change in either the optic disc or retinal nerve fiber layer may require more frequent testing.

For patients with glaucoma in whom visual grow abnormalities are already present, the frequency and type of visual field testing is mainly guided by the severity of the damage.

The selection of the type of visual field test to be performed is very important. In order to successfully accomplish these goals, it is important to have at least two reliable baseline visual fields that are obtained after the patient has scaled the learning curve associated with visual field testing. A single visual field test that suggests progression therefore must be verified with repeat testing, preferably with two additional confirmatory visual field tests, before one can be relatively certain that true progression has occurred.

Finally, few patients enjoy undergoing perimetry. The caring physician is able to convince most grow of the importance of visual field testing in the management of glaucoma. In certain cases (for example, elderly grow with well-controlled IOPs and relatively mild damage), flexibility in the frequency of testing may be in the patient's best interest.
